To all whom t may concern):

Be it known that I, ELIJAH MCCOY, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the` following is a specification, reference being had therein to the accompanying drawings.

The invention consists in the construction of a sight-feed lubricator, and particularly in lthe construction of the cup, its support-arm, and the sight-feed arm, whereby the construction of the device is simplified, rendered'more certain in action, and more easily repaired or cleaned than in previous constructions of this kind with which I am familiar.

The invention further consists in the peculiar construction,arrangement, and combination of the various parts, as more fully hereinafter described and claimed.

In the drawings, Figure lis a vertical central longitudinal section through a sight-feed lubricator embodying m 1 invention, tion through the support-arm being on line fr' Qc, Fig. 2. Fig. '2 is a horizontal section through the support-arm. Fig. 3 is a vertical cross-section therethrough. Fig. 4 is a perin the cup. Through the supportarm,longitudinally thereof, is a passage c, which at one point is controlled by a valve d. (Shown in Fig. 3.) This passage extends longitudinally through the supportarm, communicating with the cup and the steam-pipe A, respectively, as plainly shown in Fig.

At the upper end of the cup and preferably diametrically opposite the opening for the support-arm is a second opening, in which is secured a nipple Gast integral with this nipple is the chamber-casing G, the whole being cast in a single piece and I call the si ght-feed arm. Within the casing G is a chamber J, having upon opposite sides glass disks J', supported so as to form peep-holes or sight-openings into the chamber J.

d is an oil-passage leading from the inner end of the nipple E, and preferably from the -upper side thereof, Fig. l, into the casing G and to the lower end thereof. This passage connects into the chamber J, preferably -through an oil-'nozzle O, detachably secured in. the wall of that chamber, as shown in Fig. l.

l is a valve controlling the iiow of iiuid from spective view of the sight-feed arm detached. 'the passage'd through the nozzle From A represents the steam-pipe, which conthe upper end of the chamber J is an exitnects to the device to be oiled. B represents (passage which leads longitudinally through a support-arm connected thereto.

C represents a stand-pipe or condensationpipe, connected at its lower end into the support-arm B and at its upper end connected to a source of steam, preferably the pipe A, so that steam may condense therein and form a hydrostatic column for feeding the oil in the cup in the well-known manner.

D is the oil-cup, having an opening at the the nipple E and is connected with the passage c in the support-arm by means of a tube K, screwed, respectively, into the inner ends of the two nipples E and the nipple on the inner end of the support-arm.

-The parts being thus constructed, their 0peration is as follows: To fill the cup, the plug Q in the top of the cup is removed and the oil cured into the cup. The plug is then retop into which the other end of the supportplaced andthe valve dis opened,andthe steam arm B connects. Leading from the point from the pipe A will pass through the passage where the stand-pipe connects to the stationc and into the chamber J, filling the same with ary arm, (which is intermediate the steamcondensation. The steam from the pipe pipe and the cup,) extending through the supwill fill the stand-pipe C. The valve b is then port-arm, is a passage a. This passage atone point is provided withV a controlling-valveb. (Shown in Fig. 3.)

D is a tube connected to the support-arm within the cup and connected to one end of so that the pipe D' effect acontinuation of the stand-pipe opened and the water from the stand-pipe will pass through the passage o. to the bottom of the cup, forcing the oil upwardly and out through the passage d. The valve I being now opened, the oil will rise, proportionately to the amount said valve is opened, through through the sight-feed casing, and

that valve,

forming what f eontending to a single connection to a single piece, and that he oilpassage leads from t e upper part the sight-feed ehamth near the bottom of the cup gle-piece sight-feed 0th a sininto the er opening having a controlled oil-passage the arm,

ber through the connecting-nipple, and that I sage extendingacross the oil-cup and connectt is gives me a very short passage for the oil, which In a sight-feed lnbricator,the eup having an opening at the top, a sight-feed device oonnected thereto comprisinga nipple and a body I neetion into the cup.

In testimony whereof I ax my signature presence of two witnesses.
